3. The plaintiff, in response to their letter dated 27.2.1992 informed the defendants, vide letter dated 28.2.1992, that in course of its business the plaintiff is required to furnish necessary Bank Guarantee against the advances received from its clients and the plaintiff being a public sector undertaking, its clients are mostly public sector undertakings and Government organizations except a few private parties, so a request was made to waive any commission if payable for issuance of such Bank guarantees. The plaintiff informed that necessary margin money for the Bank guarantee would be kept in deposit with defendants. Thereafter plaintiff submitted two applications dated 24.3.1992 and 30.3.1992 respectively for sanction of bank guarantee limit of Rs. 25.00 crores each totaling to Rs. 50.00 crores to the defendants as the plaintiff was expecting a big order from a public sector undertaking.

The plaintiff, immediately on receipt of the aforesaid sanction letter, informed the defendants by its letter dated 27.7.1992 that the plaintiff cannot ensure the defendants for keeping the deposits of the order mentioned in the defendants letter dated 14.7.1992.
